This appendix suggests solutions for problems you may encounter in installing or
using the OfficeConnect Gigabit VPN Firewall, and provides instructions for
using several IP utilities to diagnose problems.
Contact Customer Support if these suggestions do not resolve the problem.
Problem
Troubleshooting Suggestion
LEDs
Power LED does

product is turned
on.
Verify that you are using the power adapter provided with
the device and that it is securely connected to the
OfficeConnect Gigabit VPN Firewall and a wall
socket/power strip.
LINK WAN LED
does not illuminate

Verify that an Ethernet cable like the one provided is
securely connected to the Ethernet port of your ADSL or
cable modem and the WAN port of the OfficeConnect
Gigabit VPN Firewall. Make sure that your ADSL or cable
modem is powered on. Wait 30 seconds to allow the
OfficeConnect Gigabit VPN Firewall to negotiate a
connection with your broadband modem.
Problem
Troubleshooting Suggestion
LINK LAN LED
does not illuminate
after Ethernet cable
is attached.
Verify that the Ethernet cable is securely connected to
your LAN hub or PC and to the OfficeConnect Gigabit
VPN Firewall. Make sure the PC and/or hub is turned on.
Verify that your cable is sufficient for your network
requirements. A 100 Mbit/sec network (100BaseTx)
should use cables labeled Cat 5. 10Mbit/sec cables may
tolerate lower quality cables.
Internet Access
PC cannot access
Internet
Use the ping utility, discussed in the following section, to
check whether your PC can communicate with the
OfficeConnect Gigabit VPN Firewall’s LAN IP address (by
default 192.168.1.1). If it cannot, check the Ethernet
cabling.
If you statically assigned a private IP address to the
computer, (not a registered public address), verify the
following:
Check that the gateway IP address on the
computer is your public IP address (see the Quick
Start Guide chapter, Part 2 for instructions on
viewing the IP information.) If it is not, correct the
address or configure the PC to receive IP
information automatically.
Verify with your ISP that the DNS server specified
for the PC is valid. Correct the address or
configure the PC to receive this information
automatically.
Verify that a Network Address Translation rule has
been defined on the OfficeConnect Gigabit VPN
Firewall to translate the private address to your
public IP address. The assigned IP address must
be within the range specified in the NAT rules. Or,
